Family: Picornaviridae

Genus: Ludopivirus

 

Distinguishing features

The genus is distinguished on the basis of genetic characters. 

Virion

Morphology

No details are available on the morphology of virions. 

Nucleic acid

Genome (Boros et al., 2018): c. 8,051 nt (5′-UTR: 529 nt; ORF: 7,257 nt; 3′-UTR: 265 nt). The location of the cre has not been identified. 

Genome organization and replication

Genome layout:

VPg+5′-UTRIRES-[L-1AB-1C-1D/2AH-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,419 amino acids. There is an L protein with unknown function. The 1AB protein remains uncleaved. The 2A protein has an H-box/NC sequence motif. 

Biology

No virus has been isolated. Viral RNA was detected in a cloacal sample of greater white-fronted geese (Anser albifrons). 

Derivation of names

Ludopivirus: derived from Hungarian lúd (goose) and picornavirus

Species demarcation criteria

There is only a single species in the genus.
